I had a factory job done on my Ultra Varmint frame and also did my own on the new .204 ruger handi frame. All I did was polished the hammer and trigger surfaces as detailed in the tirgger hone sticky, it reduced the trigger pull from heavy to ~2.5lbs as near as I can tell, it's almost identical in pull and feel as the factory trigger job. I didn't take the UV frame apart to compare things and I don't have a trigger pull scale, I used a jug of water and a coat hanger to lift with the wire on the trigger then weighed the jug of water on an accurate diet scale. Factory was 2lbs 9oz, mine was 2lbs 7oz. The thing of it is, I did very little, used 600 wet dry paper with honing oil on the pins, hammer and trigger bores just enough to put a slight shine on em. Used an extremely fine ceramic knife stone from a lansky kit to hone the hammer and trigger engagement surfaces til the were shiny. Reassembled with tetra grease and the trigger was almost too light, but acceptable. It didn't take much time, maybe a little over an hour start to finish, total. Using Perklo's instructions help immensely with assembly, couldn't have done it without the detailed instructions, but didn't remove the firing pin mechanism since Raynor didn't mention it. I'm real happy with the results, the trigger is glass smooth with no creep and breaks like glass, just has lots of overtravel due to the transfer bar mechanism and I don't think anything can be done about that without a total reworking of the trigger, something left to the pros.
